The 2019 Mazda 6 sits in the modern sport-sedan tradition, blending sharp styling with the balanced, driver-focused character that helped Mazda distinguish the car in a crowded midsize field. Tire choice matters here because the Mazda 6 uses two different primary radial sizes depending on trim: 225/45R19 or 225/55R17. That split puts fitment first, since wheel diameter changes with the sub-model. Once the correct size is confirmed, the decision becomes more about tire character, with blackwall performance-oriented choices in both sizes and restoration-flavored wide whitewall or redline options in 225/55R17. The right selection should match the car's exact trim, wheel setup, appearance goals, and intended road use.
Which Tire Size Is Right for The 2019 Mazda 6
The 2019 Mazda 6 uses two primary tire sizes, and the correct choice depends on the exact sub-model and wheel diameter. 225/45R19 fits the 19-inch wheel setup used on Grand Touring, Grand Touring Reserve, Signature, and Touring trims, while Sport uses 225/55R17 on a 17-inch wheel. Before comparing tires, confirm the trim and verify which wheel package is actually on the car, especially if wheels have ever been changed.
Fit(s): Grand Touring, Grand Touring Reserve, Signature, and Touring
Construction: Radial|Rim: 19 in
225/45R19 is a metric radial size in which 225 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2019 Mazda 6, this size belongs to trims equipped with the 19-inch wheel package and keeps the fitment in a modern radial format. Available choices center on BFGoodrich blackwall tires across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is the right starting point when the car has 19-inch wheels and the goal is to stay with the proper trim-specific fitment.
225/55R17 is a metric radial size where 225 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2019 Mazda 6, this size is used on the 17-inch wheel setup and remains a modern radial fitment rather than a vintage sizing format. BFGoodrich options in this size include blackwall g-Force series tires as well as Silvertown Radial choices with wide whitewall and redline sidewall treatments. It is the size to evaluate when the car carries 17-inch wheels and the buyer wants either a conventional modern look or a more distinctive appearance.
Tire fitment on the 2019 Mazda 6 varies by sub-model, so identifying the exact trim is the first step before comparing tire options. Most covered trims use the 19-inch setup, while the Sport uses a different 17-inch fitment that opens up a broader range of sidewall styles.

2019 Mazda 6 Grand Touring
The 2019 Mazda 6 Grand Touring uses the 225/45R19 radial fitment tied to the 19-inch wheel package. Tire selection here is mainly about choosing among blackwall BFGoodrich performance-oriented series while keeping the correct wheel diameter and trim-specific size.
The 2019 Mazda 6 Grand Touring Reserve also uses the 225/45R19 radial setup. That keeps the focus on comparing tire series within the correct 19-inch size rather than deciding between multiple primary fitments.
The 2019 Mazda 6 Signature uses the same 225/45R19 radial size as the other 19-inch trims. Choosing a tire for this sub-model comes down to staying with the proper 19-inch fitment and selecting the product character that best suits the car's road use.
The 2019 Mazda 6 Sport uses the 225/55R17 radial fitment on a 17-inch wheel. That setup brings a wider mix of product personalities, including blackwall performance tires and Silvertown Radial options with wide whitewall or redline styling.
The 2019 Mazda 6 Touring uses the 225/45R19 radial size. For this trim, the key is confirming the 19-inch wheel package and then comparing the available blackwall tire series within that single primary fitment.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2019 Mazda 6 Tires for Sale
Available 2019 Mazda 6 tires center on BFGoodrich radial options in both 225/45R19 and 225/55R17. Buyers can compare g-Force series blackwall tires across both sizes, while 225/55R17 also adds Silvertown Radial choices in wide whitewall and redline styles.
Common 2019 Mazda 6 tire questions usually come down to trim-based sizing, 17-inch versus 19-inch wheel fitment, radial tire selection, and the difference between modern blackwall choices and more appearance-driven sidewall styles.
Tire Size & Fitment
What tire size fits a 2019 Mazda 6?
A 2019 Mazda 6 uses either 225/45R19 or 225/55R17, depending on the sub-model. Grand Touring, Grand Touring Reserve, Signature, and Touring use 225/45R19, while the Sport uses 225/55R17. Both are radial tire fitments, but they are tied to different wheel diameters.
The important next step is matching the tire size to the wheel package actually on the car. A Mazda 6 that has had wheels changed since new may no longer match its original trim-based setup, so checking the current wheel diameter before purchasing tires helps avoid selecting the wrong size.
What size rim does a 2019 Mazda 6 use?
The 2019 Mazda 6 uses either a 19-inch or 17-inch rim, depending on trim. The 225/45R19 fitment uses a 19-inch rim, and the 225/55R17 fitment uses a 17-inch rim. Rim diameter is part of the tire size itself, so the tire and wheel must match.
Wheel diameter should be confirmed before anything else, especially on a used car. Trim level is a good guide, but the actual wheel on the vehicle is what matters when choosing tires, and any aftermarket wheel change should also be checked for width and clearance before staying with the same tire size.
Do all 2019 Mazda 6 sub-models use the same tire size?
No, 2019 Mazda 6 sub-models do not all use the same tire size. Grand Touring, Grand Touring Reserve, Signature, and Touring use 225/45R19, while Sport uses 225/55R17. The difference is not just profile; it also changes the wheel diameter from 19 inches to 17 inches.
That means the exact trim matters before comparing brands or tire series. It also means a buyer should not assume that a tire choice for one Mazda 6 trim applies to another, because the wheel package changes the fitment foundation and can affect both appearance and tire-selection options.
Choosing the Right Tire
What should I consider when choosing a 2019 Mazda 6 tire?
Start with the correct trim-based size, since the 2019 Mazda 6 uses either 225/45R19 or 225/55R17. Both are radial fitments, so the main selection factors become wheel diameter, tire series, sidewall treatment, and how the car is actually driven rather than choosing between vintage and modern construction types.
A 19-inch setup keeps the decision focused on blackwall BFGoodrich g-Force choices, while the 17-inch setup allows both blackwall performance styles and more appearance-led Silvertown Radial options. Rim-width compatibility, load figures where stated, and the current wheel setup are all worth reviewing before making a final choice.
What sidewall styles are available for 2019 Mazda 6 tires?
Sidewall style depends on the tire size. In 225/45R19, the available choices are blackwall tires. In 225/55R17, the range is broader and includes blackwall, wide whitewall, and redline sidewall treatments, giving the Sport fitment more visible appearance variation within the correct size.
That matters if the Mazda 6 is being styled for a particular look rather than simply replaced with a conventional modern tire. Sidewall treatment does not change the need to keep the correct size and wheel diameter, so appearance should be chosen only after the trim and 17-inch versus 19-inch setup are confirmed.
What tire series are available for the 2019 Mazda 6?
The 2019 Mazda 6 is offered with several BFGoodrich tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial. The three g-Force series appear in both primary sizes, while Silvertown Radial appears in 225/55R17 with more appearance-oriented sidewall styles.
Series choice helps narrow the tire's character, but it still comes after confirming the proper trim-based fitment. Once the correct size is established, comparing sidewall style, stated rim-width range, and any load information attached to the specific product makes the grid easier to sort through.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mazda 6?
A period-style approach on a 2019 Mazda 6 still starts with the correct modern radial size for the trim. The most appearance-focused options appear in 225/55R17, where Silvertown Radial tires are available alongside blackwall choices, while 225/45R19 remains centered on contemporary blackwall performance-style tires.
That makes the 17-inch Sport fitment the more flexible starting point for a distinctive presentation. A buyer aiming for a very specific visual theme should balance sidewall style with the car's existing wheel package and overall look, rather than assuming any decorative sidewall automatically suits every Mazda 6 trim.
How does tire construction affect the appearance of a restored 2019 Mazda 6?
On the 2019 Mazda 6, construction does not create a bias-ply-versus-radial appearance decision because both primary fitments are radial. Visual character comes more from the wheel diameter and sidewall treatment, especially in 225/55R17 where blackwall, wide whitewall, and redline options create very different presentations.
That means appearance planning should focus on size, wheel package, and sidewall style rather than construction change. A 19-inch trim will keep a more modern visual profile, while a 17-inch setup offers more room for styling choices that stand out without departing from the correct radial format.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mazda 6?
Yes, modifications can affect tire fitment on a 2019 Mazda 6 even when the original tire size is known. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how a 225/45R19 or 225/55R17 tire sits in the wheelwell.
That is why the current setup matters more than assuming the car still matches its original trim package. Clearance at full steering lock, suspension travel, and wheel-to-tire compatibility should all be checked any time a Mazda 6 has been customized or when a newly purchased used car shows non-original wheels.
What should I inspect before driving a 2019 Mazda 6 on new tires?
Before driving a 2019 Mazda 6 on new tires, inspect the wheel condition, confirm the tire size matches the wheel diameter, and verify proper inflation. It is also smart to look over the valve stems and check that there is no rubbing at the strut, fender liner, or outer edge of the bodywork.
A short local test drive can reveal vibration, pull, or contact issues before the car is used at highway speed. Rechecking pressure after installation and making sure lug hardware and alignment are in good order helps the new tires wear properly and lets the Mazda 6 behave as intended on the road.
How often should tires on a 2019 Mazda 6 be inspected?
Tires on a 2019 Mazda 6 should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, cuts, bulges, cracking, and slow air loss are all worth checking throughout the year, especially if the car sees seasonal use or spends long periods parked between drives.
Routine inspection is especially useful on a car with low annual mileage because age and storage conditions can matter as much as tread depth. Looking at the tires before longer trips and after any impact with potholes or curbs helps catch issues early and protects the fitment choice already made.
